If you are a programmer who works in the scientific or mathematical fields, you may find yourself needing to use the mathematical constant “e” in your code. In this tutorial, we will explain how to write “e” in Python NumPy.

Steps

Step 1: Import the NumPy library

Before we can use NumPy in our code, we need to import it. To do so, we will use the following code:

Here, we have imported NumPy and given it the alias “np”. This is a common convention when working with NumPy.

Step 2: Use the exp() function to generate “e”

The NumPy library includes a function called “exp()”, which generates the value of “e”. To use this function, we will use the following code:

In this line of code, we are using the “exp()” function to generate the value of “e”, and assigning it to a variable called “e”.

Step 3: Display the value of “e”

We can now display the value of “e” in our code. To do so, we will use the following code:

This line of code will output the value of “e” in the console.

Conclusion

In this tutorial, we have explained how to write “e” in Python NumPy. By following the steps outlined in this tutorial, you can easily generate the value of “e” in your NumPy code.
